Your instinct would be... what then?
I've just discussed this matter with my local baseball-cap repairman. He assures me that Michigan baseball caps are available by special order in West Virginia. He sees nothing in that baseball cap that is inconsistent with baseball caps available to genuine union thugs.
Most likely a non-reaction (physically). Frustration, sadness that I'm in a position where I can't do anything about it because the situation will get more violent and ugly for my kids if I escalate the confrontation by fighting back.
